To all whom t may concern:

Be it known that l, JEssE Gr. ViNcENT, a citizen of the United States, residing at Detroit, in the county of lVayne and State oi' Michigan, have invented certain new and useful Improvements in Addingltliachines, of which the following is a specification.

- One object of the present invention is to equip ana-deling and listing machine with an improved form of item counter which can lhe variously'adjusted for the purpose of predetermining the number of itemizing operations to loe performed lovy the machine in any series, the arrangement being` such that upon the completion of the series no further itemizing can loe done until the counter is re-set. Thus the operator will he prevented from inadvertently over-running the previously estimated number of itemsI tor making up a column. A Jfurther object of the invention is to provide for automatically resetting the item counter an accompaniment to the taking of a total. A still fun ther object of the invention is to provide for eliminating the locking function at will so that whenever desired items can he indefinitely counted.

With these and incidental objects in view the invention consists` in certain novel Jr`eatures oi construction and combinations of parts the essential elements whereotl are recited in the appended claims and a preferred forni of embodiment ot which is illustrated in detail in the accon'ipanying draw ings and fully described hereinafter.

Of said drawings. Figure l represents in left side elevation an adding and listing machine of the well-known Burroughs type, the casing and certain cross-shafts and stud:-A` appearing in section as well as the carriage attachment at the rear and portions of the item counting and automatic locking mechanism of they present invention which is shown applied to said machine; Fig. 2 represents the item counting and automatic locking mechanism on an enlarged scale in left side elevation together with portions of the adding machine frame; Fig. 3 shows a portion ofthe machine keyboard in left side elevation with some parts broken away and in section. also ,parts of the total set ting devices ot the machine together with parts ot' the automatic locking mechanism.-

taken on a vertical'section inwardlybeyond the item counter index devices; F1g. 4 rep item counting and automatic locliing mech anisni detached in pnspectiva The invention is il .ustrated in the present caseas adapted and applied to the well known Bu 'ro'nghs adding and listing inachine t'or the details ot which reference may be had to the llilliarn l'urroughs Patents Nos. %,953 and 505,0?8 oi: June l) 1S. "5. hut it to he understood that the inv vien is not necessarilj.1 limited to'th'is particular adaptation hut may he. applied to other types ot adding and listing machines. 'lhe machine as here shown employs the usuali columns of 'depressihle amount lie-ys which operato through hell crank levers to thrust rearwardli,v the slotted strips plates 2li. the latter adapted to be caught i.

and held rearward hy the engagement there with ot springactuatml detent pawls 228 in the usual manner. The reference numeral '202 designates the usual round har which operates to disengage said detent parvis from the strips and thrust the latter torward, this bar forming part olf a bail coinprising end arins Q19 secured to a rock-shaft 207. This hail is as usual drawn rearwa diy Dy a coiled springY 1881 and arranged to he rocked forward against the of said.

spring and then released to he restored to rearward position, in each operation of the machine toward the close thereof. By the present invention it is proposed to automatically lock this hail in its t'orward position when a predetermined number ot items have been' recorded and registered hy the machine. To this end one of the arms 219 of the key-releasing bail hasa depending portion 219a carrying an outwardly projecting square lug 1859. This lug` is adapted to loe engaged by a similarly formed notch 1859- in the upper edge of the horizontally and forwardly extending, arm i813 of a hell lli) crank lever pivoted upon a frame stud 1850 and having a depending' arm 1813, It will be seen that the locking of the bail in its forward position locks the entire key-board so far as the amount keys are concerned because of preventing any rearward movement of the detent strips 214. This locked relation of parts is illustrated in Fig. Shy full lines. This ligure of the drawings also illustrates the operation of unlocking the amount keys by the action of depressing the total key 295. The latter is of the familiar Burroughs type, being part of a bell crank 'lever 227 whose depending arm is coupled through slot-and-pin connection with a link 226 which is in turn jointed to the lower end of an arm 227 hung from a cross-shaft 200. In the present instance an additional link 1810 is jointed to the lower end of said arm 227a and is slotted at its rear end to embrace a stud upon. the bell crank arm 1813.

lThrough these connections it will be seen that depression of the total key will result in swinging said bell crank arm rearwardly and correspondingly depressing the horizontally extending arm 1813 and disel'lgaging it from the lug 1859 whereupon the spring 1881 Will draw the detent-controlling bail rearwardly. The depressionl of the bell crank arm 1913 is'against the stress of a spring 1880 which tends to press an upturned extension 1813b of the said arm 1813 into engagement with the periphery of a disk 1822, said extension being formed at its upper extremity with a laterally turned foot 1813c adapted to rideupon the periphery of said disk and to en ter a notch 1822 therein when the locking operation takes place. One side of said notch is abrupt but the opposite side is inclined so that by manipulation of the disk the foot can be cammed out ol engagement with the notch and the lever thus displaced so as to unlock the bail independently of the total key connections if desired,v the slot in the rear end of the link 1810 providing for this as well as for the locking movement ot' the lever independently of said link. l

The notched disk above mentioned is the medium through which the automatic locking of the key-board can be timed to take place at the conclusion of recording and registering a certain number of items as predetermined by the operator. To this en d the disk is arranged to be turned and set at various positions and then returned step by step until the notch arrives opposite the end of the lbell crank extension 18131). Said disk lis secured to the inner reduced end of Aa stud 1831 (Fig. 7) journaled in a short sleeve 1830, the latterV being in turn journaled in the heads 1834 and 1835 of' a spring barrel 1836 which occupies a circular recess or aperture in the supporting frame-work of the machine and is'securely held in place by a screw 1836. Said stud and sleeve are shouldered to insure their proper longitudinal relation and the stud is formed on its outer end with a pair of lugs 1831 (Fig. 9) to engage notches 1832 (Fig. 12) in the inner end of a relatively long sleeve 1832 which extends through the left-hand side of the machine .casing (Fig. 7) and projects considerably beyond the same. This longer sleeve lies at its inner end within the outer portion of the shorter sleeve 1830 and at its outer end is longitudinally slotted in one side as shown at 1832b to receive a key 1892 carried by a knob 1833 surrounding the outer portion of said longer sleeve. It will now be seen that by turning said knob the notched disk can be turned through lthe medium of the sleeves 1831 and 1832 and the engagement of the key 1892 with the slot of the latter. The knob 1833 has compounded with it a disk 1833 formed with a peripheral flange 1837 marked offl into graduations and inscribed with numerals as shown in Figs. 4 and 5 constituting an item scale by which to set the notched disk. A pointer 1890 fixed to a boss on the machine frame serves to indicate the zero position of the notched disk and to guide the o )eratorl in setting said disk by turningl the knob 1833 from left to right.

The inner edge ol the iiang'e 1837 is formed with saw-teeth 1837 for interlocking with similar teeth 1838 upon the peripheral flange 1833 of a disk 1839 having a tubular boss 1839 loosely embracing the sleeve 1832 behind a flange 1832c thereof. The peripheral flange 1833 is marked off into graduations the same as the peripheral flange 1837 and is likewise inscribed with numerals to constitute with `said graduations an item scale but the numerals run in the opposite direction to those upon said flange 1837 as this latter scale is used to munt the operations of the machine while the zero point of the first-described scale is, being moved back step by step.

The connections for turninur the flanged t .b fr disk 1839 ste) b f ste) are ott-he followin pounded through the medium of a suitable' hub with a ratchet wheel 1819. The latter is arranged to be engaged and turned one step in each operation of the machine by a pawl 1815 pivoted upon a stud 1860 (Fig.v

2) which pivotally unites a vertical bar 1811 and an arm 1814 pivoted upon the stud 1850. A spring 1882 connectssaid arm with the tail of the pawl holding the latter yield'- There is secured upon theingly againsta stud 180e on said arm, the

pawl being normally withdrawn from engagement with the ratchet wheel but readyv l to engage and turn the same when the bar 1811 thrust upwardly. This baris pivotally connected at its lower end through the medium of a stud 1855 with tlfeJ rear arm of embracea roller stud 1899 upon an arm of the familiar Burroughs lever '813, see Fig.

1. lt will be seen that the oscillations ofV said lever 813 will result in reciprocating; the pawl through the connections described so that in each operation of the machine the r:,s.tehet wheel will be turned one step. 1t will further he seen that this intermittent 'turning of the ratchet wheel will conve)v movement .through the gearing described to the ilanged item counting' disk 1839 so that 'the scale on the latter will be moved past the pointer 1890, which will therefore denote `on .said scale 4the '.nmnher of operations which the machine has performed 'in an)y given series. at the same-time the flanged disk 1833*L will be turned step by step by reason of the interlocking of the saw-teeth as hereinbefore mentioned so that the notched disk 1822 will be moved until itsA that forward swingwof the detent-control'- ling bail must ensue oe-forethe locking level'l .can move upward and engage its notch with the lugv 1859 of said bail, see Fig.

1t has beenbefore stated that the knob 1838 and the sleeve 1832 are connected through the medium of a key 1892 and a slot 1832, This is for the purpose of perinitting the flanged disk 1833, to be drawn outwardly and its saw-teeth disengaged from those of the flanged disk 1839. When this has been done the first-mentioned disk can of course be rotated indel)endenthv ot' the other disk. Thus in order to set the parts for lockingF the key-board after a predetermined number of operations of the machine the operator simpl)Y pulls the knob 18323 (,uitwardl)Y and then turns it to the right until the proper graduation comes opposite the pointer 1890 when the knob released. T he two disks are drawn into engagement by a` spring' 1885 contained within a. recess of the 'knob 1853 andsm'r-omnlingr the enlarged portion of a bolt 185i which extends through the sleeve 1839.` being' shouldered to bear against the outer end thereof. The slotted head of this bolt overlies the'spring;

121561885, the latter bearing at the oppositeend,

.wai-div b V depression of the total key.

against the base of the recess in the knob.

The reduced and'sc1'ewtlneaded inner end of said bolt engages a tapped bore of the stud 1831, see Fig. 7. It will be seen that the construction of parts just described provides for the spring` 1885 constantly exerting` itself to enforce engagement between the two flanged disks.

It has been stated that one of the objects of the present invention is to provide for rey setting/the item counter auton'iatically and to this end a coiled spring 1886 is placed within the barrel 1886 and secured at its inner end to the sleeve 1830. The outer end of` the springis preferably not rigidi)7 connect- 80 ed with the barrel but frictionally engaged therewith so as to simply secure an average tension sufficient to turn the counter through one backward revolution. This prevents continued winding of the spring when the counter makes more than one complete forward rotation., the spring' slipping' to prevent excessive winding. Of course it will be understood that the step-by-step turning` of the notched disk is against the tension of i this .spring 1886. To prevent retrograde movement of the ratchet wheel when the actuating' pawl withdrawsy a restraining pawl 1816 is en'lployed, the same being` pivotally nfioun'ted upon a cross-rod or shaft 202b 95 and held against the ratchet wheel by a spring;` 1888 connectingl its tail with' the frame of the machine, see Fig. 6. 1n order to bring about the )fe-setting of tlieounter by its motor spring' 1886 it is of course neces- 100 sary to displace this restraining pawl in addition to disengagging` the locking' lever from the notched disk. To this end the swinging arm 227 of the total settingl devices is formed with a rearwardly projecting in- 105 clined linger 18161 which is arranged to act against the under-edge of the tail of the pawl 18115 when said swinging' arm is moved rearl is desirable to provide for definitely stopping' the counter when re-set by its motor l spring so as to insure a fixed starting' point and to this end a. disk 1818 is employed, the sainehaving the peripheral contour of a snail-cam. Said disk embraces the sleeve 1830 as shown in Fig'. 7 and is formed with `lugs to occupy notches 1818a in said sleeve (Fig. 10) so as to turn therewith and hence with the flanged index disk 1839. A stoparm 1817 is pivoted on a stud 1856 carried by the frame of the machine and this arm is drawn against the periphery of the disk 1818 by aspring 1881. So long as operations of the machine are being' count-ed'said arm simpl',T rides upon the periphery of the 125 disk dropping` past the shoulder thereof as each complete rotation is made but it will be seen that this arm always stands readyv to stop tile-.counter at the same point when itis re-setfloy the spring 1886, by presenting its end to the abrupt shoulder of the disk as bail is locked.

drawn out'and turned to the left to cam the shown in Figs. 1 and 6.

When it is not desired to place a definite limit to the number of' items in a series but at the same time to keep count of the items' it is only necessary to keep the flanged disk 1833a out oi engagement with the flanged disk 1839. To facilitate this adjustment the same plate 1891 of which the pointer 1890 forms a part is provided with an outwardly projecting arm 1893 notched in its end to receive a stud 1894 which projects from the peripheral flange 1837 ofl the disk 1833, see Fig. 4. The arm 1893 projects sufficiently to hold the toothed flanges ot' the counter disengaged so long as the stud 189-1 is against. the notched end of said arm. This adjustment can be readily brought about by simpl)7 pulling the knob 1833 outwardly and turning it slightly to the left and then releasing it.

The operation of the invention will be more or less apparent from what has already been stated. Vith the parts standing at normal, that is with the '/iero marks of -the two scales registering as shown in F ig. 4. should the operator desire tolset the machine for a certain number of' items he simply draws out the knob 1833 and rotates it to the right until the mark on the outer scale indicating the desired number of items comes opposite the pointer 1890 and then releases the knob whereupon the flanges ot' the two index disks become `interlocked. Then as one item after another is recorded and registered in the machine the counter is turned step by step carrying the zero mark of the outer scale back-toward the pointer and advancing the inner scale past said pointer to show the count. When the predetermined number of operations have been performed the notched disk will have been brought to position for receiving in its notch theI end of the locking lever extension. Then wlen the detent-controlling .bail is rocked forward its lug1859 is carried over the notch of said locking lever and the latter rises and the The knob can then be again locking lever out of 'the notch whereupon the bail Will-be drawn back to its normal position by the spring 1881 and the keyboard unlocked; then the knobean be turned to the right to set the lock for taking effect after the salne number ofoperations of the machine as before or for a different number, While count of the total number of both series ofl operations is preserved on the inner scale. However, as in most cases either a grand total or a sub-total would be struck upon the conclusion ol the listing of' the predetermined number of items constituting a series, the above manipulation of the knob 'would not ordinarily be pursued. As before explained, the mere depression of the total key has the effect of' withdrawing the locking lever from the notch of the disk 1822 and disengaging said lever from the lug of the detent bail and also displacing the restraining pawl. This results in the two flanged index disks being turned back t0-v gether by the spring 1886 so that the counter is automatically re-set for a repetition of the same number of itemizing operations. It will be noted in this connection that the key-A board can be caused to become automatically locked after a number of itemizing operations in excess of' those provided for by the scales shown in the present instance. Fgr example, if it is desired to lock the keyboard after 150 items have been recorded the operator will set the counter to lock after the seventy-fifth item has been recorded and registered and then upon the key-board becoming locked will simply press the total key and continue putting 'in items until seventy-five more have been recorded and registered. Thus upon the introduction of the 150th item the key-board will become locked.

lt will now be seen that the above de-f scribed construction is well calculated to' thoroughly fulfil the objects primarily stated. At the same time it'will be understood thatthis construction is susceptible ot' considerable modification within the scope of the invention. j
